Title: Management system of lubricating oil level in engine
IPC: F01M11/06
Filed: 1992-03-30
Abstract: PURPOSE:To automatically hold the lubricating oil level in a range between the determined high level and low level by closing and opening first and second solenoid valves respectively by the oil level detection in an oil pan by means of an oil level detector. CONSTITUTION:When the oil level in an oil pan 12o reaches the high level H, No.1 solenoid valve 18 is closed, and No.2 solenoid valve 19 is opened, then the lubricating oil is returned into a sub tank 21 from the oil pan 12o by opening a pressure response valve 20b under pressure of a pump 14b. On the other hand, since a part of the supplied lubricating oil is circulated in a pump 14a by opening operation of the second solenoid valve 19, the pressure response valve 20a is not opened, so that, the oil level in the oil pan 12o is lowered. And when the oil level reaches the low level L, the solenoid valves 18, 19 are placed in opening and closing operation by an oil level detector 13, respectively. Therefore, the amount of oil reaches again the high level H, and the control operation mentioned above is automatically repeated. Then the oil level is automatically held between both levels of H to L.

Filed: 1979-08-11
Abstract: PURPOSE:To adjust the dispersion of the output in a simple way by adjusting the relative distance between the bobbin for the primary winding and the bobbin for the secondary winding. CONSTITUTION:In transformer cores 1 and 2, a bobbin 3 for the primary winding and a bobbin 4 for the secondary winding are slidably installed, and the output is adjusted by adjusting the relative distance between the bobbins 3 and 4.

Title: Irregular magnetization preventing system for transformer
Inventor: YOKOYAMA HIDEO
IPC: H02M1/40
Filed: 1981-06-30
Abstract: PURPOSE:To prevent the irrgular magnetization of a transformer by preventing the input of ON signal to a switching transistor even when the ON signal is inputted at the time when the energization of the transistor is not released. CONSTITUTION:When the width of an ON signal from a rectangular wave generator becomes wider than the prescribed value and an OFF signal becomes narrow, the ON signal of the generator is inputted while a current for releasing the energization is flowing through a diode D1. On the other hand, the terminal of a diode D4 of an AND circuit 1 is ''L'' level, and the ON signal is not applied to the input of a transistor Tr until the current for releasing the energization is eliminated. Accordingly, the transformer T is not irregularly magnetized (saturated).

Title: Spindle motor
Inventor: TAKASU SHUHEI
IPC: F16C17/10
Filed: 1993-04-28
Abstract: PURPOSE:To allow reduction in the height of a motor by making a groove on one of the truncated conical rotary shaft section or a bracket having a through hole and an inclining face opposing the outer peripheral inclining face of the shaft section. CONSTITUTION:Electromagnetic interaction takes place between a stator coil 20 and a rotor magnet 31 to cause rotation of a rotary mamber 11. Consequently, lubricant is urged to move from the opposite ends toward the center in a groove 33 made on the outer peripheral inclining face 28 at the rotary shaft section 21, and thereby a dynamic pressure bearing section A functions to float the rotary shaft section 21. When the gravity on the rotary member 11 side balances with the floating force of the bearing section A, the motor can be rotated smoothly. Since the bearing section A has the bearing function in the thrust and radial directions, the bearing section B on the bottom race may be eliminated in some cases and the height of the motor can be reduced.

IPC: H04L29/10
Filed: 1987-04-28
Abstract: PURPOSE:To transmit carrier detecting signals without stopping the carriers on a line, by sending the ON/OFF signal of the transmission requesting signal of a terminal device by adding the information to transmitting data and detecting ON/OFF information from received data, and then, generating the ON/OFF information of the carrier detecting signals corresponding to the ON/ OFF information detected from the received data. CONSTITUTION:When the transmission requesting (RS) signal of a terminal device (DTE) 4 is ON (OFF), a pseudo carrier signal transmitting circuit 1 transmits transmitting data (SD) from the DTE 4 after inserting RS 'ON (or OFF)' information into the SD. A pseudo carrier signal transmitting adaptor 3b monitors received data (RD) and detects the RS 'ON' or RS 'OFF' information at a pseudo carrier signal receiving circuit 2. When the RS 'ON (or OFF)' information is received, a carrier detecting (CD) signal is turned on (or OFF). A host device (HOST) 7 can detect the CD signal corresponding to the RS signal of the DTE 4 by means of the pseudo carrier signal transmitting adaptor 3.

Abstract: PURPOSE:To safely feed a disk by providing the disk player with a 1st control means for rotating a magazine until a specified disk housing groove reaches a position opposite to a disk feeding/ejecting part and a 2nd control means for opening a shutter. CONSTITUTION:When a disk is not fed again during a period of the lapse of a fixed time after the shutter is opened, the shutter is controlled to close at the time when the fixed time has elapsed, and when a disk is fed again, the shutter is controlled to close after the lapse of the fixed time from detecting this disk. By this method, shutter closing operation can be automated. Moreover, when a smaller diameter disk than a disk having a regular diameter capable of reproducing a signal is fed, the feed of this small diameter disk is detected, and the disk is automatically ejected to a disk feeding/ejecting part.

Abstract: PURPOSE:To facilitate manufacturing and to make it possible to perform highly accurate measurement without being effected by the magnetic field generated from another conductor by providing a polarization-plane preserving optical fiber in parallel with the axial direction of the fiber in the hollow part of a coil-shaped conductor. CONSTITUTION:A polarization-plane preserving optical fiber 6 is fixed with a supporting stage 4a in the hollow part of a coil-shaped conductor 1. The supporting stage 4a is fixed to the inner side of the conductor 1 so that the vibration of the fiber 6 by mechanical force is prevented and the fiber 6 agrees with the axial direction of the conductor 1. A polarize 9 and an analyzer 10 are provided at both ends of the fiber 6. The current flowing through the conductor 1 by Faraday effect is detected. The ratio between the magnetic field generated from the conductor 1 and the magnetic field generated from another conductor 7 can be made large by providing a long light path in parallel with the magnetic field generated from the conductor 1. The accuracy of an attaching angle can be kept readily owing to the length of the light path. Therefore, the highly accurate measurement can be performed at a low cost.
